It supports multi-language capability and provides prebuilt images for various hardware types. ## Choose when ### Choose fastrtc if… - fastrtc is primarily JavaScript; Kokoro-FastAPI is Python. - License: fastrtc is MIT, Kokoro-FastAPI is Apache-2.0. - Tags unique to fastrtc: artificial-intelligence, hacktoberfest, hacktoberfest2025, llm. - Use fastrtc for projects that require pause detection in audio streams as it provides the specific ReplyOnPause feature. ### Choose Kokoro-FastAPI if… - Kokoro-FastAPI is primarily Python; fastrtc is JavaScript. - License: Kokoro-FastAPI is Apache-2.0, fastrtc is MIT. - Requirements: Min 4 GB RAM; Requires Docker; Hardware-specific Docker images are provided for CUDA, ROCm (experimental), and CPU support.; Users without supported GPUs can still utilize the service via a CPU image.. - Tags unique to Kokoro-FastAPI: docker, fastapi, kokoro tts, multi-gpu support. - You require a solution that can auto-download models and run natively on Apple Silicon (MPS) with support via UV. ## When NOT to use fastrtc - Avoid fastrtc when the project requires real-time communication features not covered by its pause detection or text-to-speech services. - Do not use fastrtc if support for multiple languages beyond what Python and this library's built-in features provide is necessary. ## When NOT to use Kokoro-FastAPI - If your hardware is not supported by the provided Docker images, for example, if you do not have a compatible NVIDIA, AMD GPU or CPU setup. - You are looking for non-Dockerized solutions. Kokoro-FastAPI focuses on containerization and might not fit environments that strictly avoid containers. ## Common questions ### What is the difference between fastrtc and Kokoro-FastAPI? fastrtc: The python library for real-time communication.
